Imma, Milena and Calogiuri go to the woods where Nunzio had seen the porcupine. Later they have a meeting with La Macchia in Imma's office.

Berardi discovers who owned the gun that killed Lenox and goes to see his superior to take himself off the case. Meanwhile, Camilla goes to Francesca's apartment to get the dogfood for Bibì.

Milena comes to Imma's office and tells her what she knows. She also makes an effort to remember a detail that might be important to the case.

Renzo has an idea for what to do about Potti. Gaetano and the district attorney go to the morgue to talk to the coroner. At school, Camilla gets a phone call from Francesca.

Poor Pietro is having trouble discussing family problems with Imma, because she is easily distracted by the case she is trying to solve. At the office the next day, she has to deal with her colleagues, something she finds distasteful, and doesn't hide very well.

At the hospital, Francesca wakes up to see Gaetano by her side. Is he there as a brother or as a cop? She explains what happened the night of the murder.

Pietro's mother shows up at his house and doesn't hide how she feels about her daughter-in-law. On the way to see Nunzio's parents, Imma and Calogiuri discuss the bank records they were able to obtain.

Camilla is in front of the hospital and gets a call on Francesca's phone. At least Camilla has the sense to warn Renzo she'll be a bit late. Renzo sees his mother-in-law outside with someone who doesn't look a bit like poor Sandra.

Imma is in the courtroom trying to get Saverio (from the previous episode) indicted. Later, she meets up with Calogiuri at the office, but there is someone else waiting for her.

Camilla finds Francesca in very bad shape and calls an ambulance. Meanwhile, Berardi interviews Lenox's secretary and hears about Paul's ex-girlfriend.

Imma goes to see her friend Pino at the museum to ask him about the fragments she saw at the reunion. She then goes to the cemetery with her mother.

Under pressure from Renzo, Camilla tries calling Francesca one last time, and this time, she answers. They arrange a meeting so Bibì can go back to her owner.

Imma is not exactly enjoying herself at the party, but she does notice something interesting, and possibly pertinent to her case. She encounters the deskmate who replaced Diana way back then.

Berardi isn't able to be honest with his boss about what leads to follow on the case. The jeweler shows up at the police station wanting his valuable pieces back. There's a little incident with Bibì at school. Berardi goes to see a guy he knows, who might be able to find out something about the jewelry.

Imma comes home. Pietro is practicing his sax. Valentina shows up in a rage. Then Imma is reminded of the class reunion dinner... the last thing she wanted to do.
